In one embodiment of the present invention, in response to an applied bias voltage selected from the group consisting of + ldc volts and-ldc, the inductance between the top and bottom electrodes is a maximum 値. With the above structure, a solid-state inductor can be provided, which has a relatively high inductance, requires a small chip area, and is suitable for integration into a conventional integrated circuit (which may be a complementary metal oxide semiconductor or a silicon-on-silicon, Or a bipolar circuit made on a compound semiconductor substrate, and a method for manufacturing the same. Furthermore, since the inductance 改变 can be changed in a 1C circuit, it can be easier to tune. -10- (6) 1231509 Doctor! This' The invention described herein makes it possible to (1) provide a solid-state inductor with a large inductance to reduce its size and a manufacturing method thereof, and (2) provide a solid-state inductor, which can be easily Change the inductance of the 1C circuit for tuning and a manufacturing method. Those skilled in the art who read and understand the following detailed description with reference to the drawings will understand these and many other advantages of the present invention. [Implementation Mode] Now, a solid-state inductor (hereinafter referred to as an inductor) and a manufacturing method thereof according to the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing Inclusive structure of the inductor according to the present invention. In FIG. 1, the inductor 100 includes a bottom electrode i 02, an electric field-treated giant magnetoresistive (CMR) film 104 covering the bottom electrode 102, and a top electrode 106 covering the CMR. Thin film 104. The CMR thin film 104 is made of a material such as Pr () 3Ca0.77Mn03 (PCMO), La0.77Ca0.3MMn3 (LCMO), Y ^ axMnOa (YCMO), and high temperature superconductor (HTSC) ) Made of materials. However, depending on the requirements, other equivalent materials may also be practical. The CMR film 104 has a thickness of about 2000 angstroms. As explained in more detail now, the C MR film 104 is exposed to 0.4 to 1 million Electric field in the range of volts / cm (MV / cm) and pulse width in the range of 1000 nanoseconds (ns) to 1 millisecond (ms). This is only one -11-(7) (7) 1231509 kinds Exemplary processing. Depending on the CMR material, the insertion material, and the desired inductance, other processing methods are realistic. The bottom electrode 102 of the inductor 100 is selected from the group consisting of aj, Au, Ti, Ta, Pt, Cu, W, Ir, AlSi or other precious metals. However, it can also be used in 1C Other conductive materials are well known. Similarly, the top electrode 106 is generally formed from a material selected from the group consisting of Al, Au, Ti, Ta, Pt, Cu, W, Ir, AlSi, or other precious metals. Provided A voltage applying device 112 is used to apply a bias voltage between the top electrode 106 and the bottom electrode 102 of the inductor 100. Generally, the inductor 100 includes a part of a larger and more complicated circuit. And the bias voltage and the relative zero potential are connected through other components, such as a transistor (not shown). Between the CMR film 104 between the top and bottom electrodes 106/102, in response to the bias voltage applied by the voltage application device 112, one of the inductors has an inductance or inductance 値 L (1 1 4). In some aspects, the voltage application device 112 may change the bias voltage to apply a row to the inductor 1000. The inductance 値 L (1 14) between the top and bottom electrodes 106/1 02 changes in response to a change in the applied bias voltage. I have developed several practical bias ranges as examples. In some aspects, the voltage application device 112 applies a voltage between the top and bottom electrodes 106/102 within a range of 0.5 to 5 dc, or -0.5 to -5 dc. However, for specific circuit applications, an ac (alternating current) voltage can also be used. Moreover, other dc voltage ranges can be used for different variations of CMR materials, CMR volume, and electric field processing. Using the above bias voltage, depending on the CMR material and the -12 · (8) (8) 1231509 geometry (volume, diameter 108, and thickness) of the CMR film 104, between the top and bottom electrodes 106/102 The inductance 114 may be in a range greater than 0.001 microhenry (// H) and less than 1 A Η. Generally, the inductance 値 L (1 14) between the top and bottom electrodes 10 6/1 2 is a maximum value in response to a voltage applied to + ldc volt or-ldc volt. However, the relationship between the maximum inductance and the bias voltage again depends on the CMR material and CMR geometry. Fig. 2 is a sectional view of a device structure in which two inductors according to the present invention are applied to an actual 1C integrated circuit. As shown in FIG. 2, the inductor 100 according to the present invention has a two-terminal cylindrical structure. The inductor can be made as a single channel hole, with a bottom electrode to a pn junction, or a metal wire connected to one part. After the front end of the process is completed, the inductor 100 can be integrated into 1C. In device A 200, the inductor 100 can be integrated into a drain junction 202. At device B 204, another inductor 100 is integrated into a gate electrode 206. The inductor (s) 100 may be applied to a semiconductor substrate using conventional deposition methods such as spin coating, sputtering, and CVD (chemical vapor deposition) methods. Moreover, the inductor 100 has a very high inductance and uses a bias control that can be changed by two orders of magnitude. Inductor 100 is part of any LC circuit whose tuning can be achieved by adjusting the bias voltage across inductor 100. For example, the inductor 100 according to the present invention may be formed using a giant magnetoresistive (CMR) film formed by a spin coating method. The CMR material may be PCMO (Pr 0.3 CaO 7MnO 3). The CMR film was applied three times for a total thickness of about 200 亳 micron (nm) to a platinum substrate. The c MR film was annealed at 650 ° C for 30 minutes after the first coating, and -13- (9) 1231509 was annealed at 5 50 ° C for 30 minutes after the second and third coatings. The top electrode 106 is also platinum, but several other metals such as Al, Cu, W, Ir, A1SI, or other precious metals may be used. Immediately after manufacture or as produced, the CMR film 104 is measured to have a resistance R due to the resistive element and a capacitance C due to the capacitive element. Figure 3 illustrates the reactance of an exemplary CMR film before electric field processing. All measurements shown in Figure 3 are resistances in series with the inductor 値. The measurement frequency is 1 MHz. The measured inductance shown is negative and therefore capacitive. Figure 3 also shows that the capacitance and resistance of this CMR film are actually independent of the bias voltage at a given measurement location. Figure 4 illustrates the reactance of this exemplary CMR film after electric field treatment.

The resistance of the CMR film 104 decreases from about 275 ohms to less than 20 ohms. The CMR film 104 becomes inductive in response to a bias voltage of -5V to -0.5V, or 0.5V to 5V. Outside of these bias ranges, the reactance of the CMR film 104 is capacitive. The maximum inductance exceeds 1 // H. By changing the bias voltage applied to the device, the inductance of the PCMO solid-state inductor 100 can be changed by more than two orders of magnitude. From the nature of the materials, it is expected that huge magnetoresistive (CMR) and high temperature superconductor (HTSC) materials are suitable for the manufacture of electrically tunable solid-state inductors.
